⁽¹⁾

Acquired IPR&D is an intangible asset accounted for as an indefinite-lived asset until the completion or abandonment of the associated research and development effort. If the research and development effort associated with the IPR&D is successfully completed, then the IPR&D intangible asset will be amortized over its estimated useful life to be determined at the date the effort is completed. During the year ended October 29, 2016, the Company acquired $27.0 million in IPR&D intangible assets in connection with the acquisition of Ruckus. The research and development efforts associated with these IPR&D intangible assets are expected to be completed in fiscal year 2017. During the year ended October 29, 2016, research and development efforts were completed on $18.1 million of the IPR&D intangible assets, and the completed IPR&D intangible assets are being amortized as core/developed technology over their estimated useful lives of five to seven years.


⁽²⁾	During the fiscal year ended October 29, 2016, $1.0 million of finite-lived intangible assets became fully amortized and, therefore, were removed from the balance sheet.

⁽³⁾

The patent portfolio license was assigned an estimated useful life that reflects the Company’s consumption of the expected defensive benefits related to this license to certain patents. The method of amortization for the patent portfolio license reflects the Company’s estimate of the pattern in which these expected defensive benefits will be used by the Company and is primarily based on the mix of expiration patterns of the individual patents included in the license.
